ROAD PLANER.

Application ierl July 11,

the county of Erie and State of Pennsylf vania, have invented certain new and useful Improvements in Road Planers, of which the following is a specification.

. This invention relates to road planers `and belongs in the class with implements employed for scraping and grading dirt roads and the like. The principal object of this invention is the production of a simple, ei:- 'lective and inexpensive road leveller in which the cutting members are set at about twenty-tive degrees angle with the length olf the road thus removing the excess dirt over and above that which is left after ruts and low spots are filled towards the center oi the road bed until depressions, low spots and other inequalities are all illed and levelled, bringing the road surface to al true grade.

This invention comprises a special corstruction and arrangement of parts wherein the cutting or scraping members are made up 0i'A angle irons. Thehorizontal sides or wings of the angle iron scraping members are deformed or distorted at the points ot their connection with the length pieces, in such manner, hereinafter illustrated and explained, as to throw the normally vertical sides or wings of the right angle irons torming `the scraping members into an inclined position rearwardly and downwardly. The backward slant resulting trom the special distorted construction of the cutting or scraping members permits them to pass over solid obstructions in the roadway without damage to the scraping members themselves or to the motive power, for example, a tractor, which is drawing the planer along the road.

In accompanying drawings which illustrate the special construction and arrangement of the parts of this invention, Fig. l represents a top plan view. Fig. 2 is a section lengthwise on the broken line 2 2 at Fig l. Fig. 3 is a section lengthwise through one of the side pieces and the successive oints or connections of the scraping members with the side piece, to illustrate the deformed or distorted portion of the hori zontal side o' the angle iron of which each cutting or scraping member is made. Figs. 2 and 3 are drawn on an enlarged scale.

1921. Serial No. 483,889.

Throughout the drawings and explanation, the sameletter is used to refer tothe same part. p

Considering the drawings, there are two parallel side pieces A and a usually `fashioned of heavy angle iron. In practice l customarily use angle iron measuring tour inches by three by five-sixteenths. The tour inch leg being arranged vertically with respect to both the scraping members anil the length irons or side pieces.

There may be any number ot diagonal cutting or scraping members referred to generally by the letter B, and near their ends each scraping member has a rigid connection b with the side pieces. Y v

ln the sectional view Fig. 2, it will be observed that' the scraping members are formed ot' right angle iron or steel. That is to say, the sides C and D are formed at right angles with each other in the common manner. The side extending horizontally is marked C and the side arranged slantingly downward and to the rear is marked D. To give the desired inclination to the side D ot' each scraping member B, the horizontal side or leg of the angle iron B is depressed or recessed at the points where the connections with the side or length pieces are located. The depressions are designated E, and it will be noted that each depression grows gradually deeper towards the rear. lt is the intention to form the depressions of such inclination and depth as to bring the side or leg D of each scraping member B into a slanting position rearwardly and downwardly of l5 degrees from the vertical. This backward slope enables the planer to rise over obstacles in the path without injury to the scraping members,

To insure rigidity and. to hold the/ parts described always in the same position, a brace bar F is secured obliquely at its ends to the side pieces A and a. It will be undei-stood that this invention is not limited to the number of parts herein mentioned, or to their size, or to the material o'l' which they are composed.

Having now described this invention, so iar as the particular construction and arrangement of its parts are concerned, it may be stated that in operation it is intended to be drawn along the road with the inclined sides or legs D ci the scraping members B in contact with the surface oi' the road.

Cil

chainG is provided at oneendi as illustrated in Fig. l, and a deformed orl catch link g or like device engages the chain. rEhe link can placed inlengagement with the chain at any desired point.- With the linlrl in the position set out in Fig. l the lplaner will be drawn along with the sides A a in linewith the length of the road. But iii' the link g be attached to the chain nearer the connection oi' the chain and the side Piece A, the scraping "members B3 ivill assume "a position more n`earl7 ati-ight angles Vto the length ofthe road, and the side pieces will takenp positionssoniewhat inclined to the line ofthe road. l `,"ho,we\c'r, theV link g be caused t re1igage the chain G near` its connection with thiesde pieces a., the inclination ofthe scraping' members with respect to the road line lwill be increased,y and the side pieces will again take np positions inclinedto the aXis of the roadway.`
